Abstract

The numerical modeling code INF&RNO (INtegrated Fluid & paRticle simulatioN cOde, pronounced “inferno”) is presented. INF&RNO is an efficient 2D cylindrical code to model the interaction of a short laser pulse with an underdense plasma. The code is based on an envelope model for the laser while either a PIC or a fluid description can be used for the plasma. The effect of the laser pulse on the plasma is modeled with the time‐averaged poderomotive force. These and other features allow for a speedup of 2–4 orders of magnitude compared to standard full PIC simulations while still retaining physical fidelity. The code has been benchmarked against analytical solutions and 3D PIC simulations and here a set of validation tests together with a discussion of the performances are presented.
